From August 4, 2016, through November 4, 2016, Gintama°: Love Incense Arc aired as a two-episode OVA. It's no secret that Gintama is a comedic and parody series, and the OVA is no exception.
Gintama, Kagura, and Shinpachi are all featured in the Gintama°: Love Incense Arc, which chronicles their search for an incense that causes its users to fall in love with the first person they set eyes on after smelling it.
It's comedic because once Tsukuyo is afflicted, her unrequited love for Gintama is intensified, and the entire district feels its effects.
